At the end of the month, they deducted 4500 rubles from me for the upcoming month without any warning. When I said I wasn't going to use the service, they replied that those are their terms. After the first month, I refused to use this useless service, realizing that it was just a waste of money. At first, they charged 20 rubles for each SMS and didn't mention the need to buy the number from the operator. Why can't they inform you about this right away? It's a scam! In the end, half of the SMS don't get delivered, and you pay 20 rubles for each or 4500 plus 3 rubles for each SMS. Do you really need this? The support is terrible.
